BackgroundData on the implementation of prehospital large vessel occlusion (LVO) scales to identify and triage patients with acute ischemic stroke (AIS) in the field are limited, with the majority of studies occurring outside the USA.ObjectiveTo report our long-term experience of a US countywide emergency medical services (EMS) acute stroke triage protocol using the Rapid Arterial oCclusion Evaluation (RACE) score.MethodsOur prospective database was used to identify all consecutive patients triaged within Lucas County, Ohio by the EMS with (1) a RACE score ≥5, taken directly to an endovascular capable center (ECC) as RACE-alerts (RA) and (2) a RACE score <5, taken to the nearest hospital as stroke-alerts (SA). Baseline demographics, RACE score, time metrics, final diagnosis, treatments, and clinical and angiographic outcomes were captured. The sensitivity and specificity for patients with a RACE score ≥5 with LVO, eligible for mechanical thrombectomy (MT), were calculated.ResultsBetween July 2015 and June 2018, 492 RA and 1147 SA were triaged within our five-hospital network. Of the RA, 37% had AIS secondary to LVOs. Of the 492 RA and 1147 SA, 125 (25.4%) and 38 (3.3%), respectively, underwent MT (OR=9.9; 95% CI 6.8 to 14.6; p<0.0001). Median times from onset-to-ECC arrival (74 vs 167 min, p=0.03) and dispatch-to-ECC arrival (31 vs 46 min, p=0.0002) were shorter in the RA-MT than in the SA-MT cohort. A RACE cut-off point ≥5 showed a sensitivity and specificity of 0.77 and 0.75 for detection of patients with LVO eligible for MT, respectively.ConclusionsWe have demonstrated the long-term feasibility of a countywide EMS-based prehospital triage protocol using the RACE Scale within our hospital network.
Background: Many syndesmosis screw fixations do not achieve success at the first attempt. Currently, there are no data available to evaluate revision of syndesmosis screw failure. Methods: A total of 160 consecutive patients who underwent syndesmosis screw fixation from 2014 to 2016 were reviewed. The current study focuses on 13 of 160 patients who underwent revision surgery and analyzes reasons, methods, and outcomes of syndesmotic screw revisions. Results: Thirteen out of 160 patients had revision surgeries. Incidence of recurrent diastasis was 92.3%. Seven out of 19 screws had broken. Two patients had screw loosening, 9 patients underwent early weightbearing, 1 patient developed osteomyelitis, 1 patient developed osteoarthritis, and 1 patient had fibular nonunion. Eleven patients underwent removal, 3 patients underwent clamp reduction, and 4 patients underwent fibular osteotomy. Six patients experienced good reduction with 0/10 pain, 3 patients experienced good reduction with some pain, 1 patient experienced poor reduction; 1 patient developed osteomyelitis and subsequent 7/10 pain; 1 patient underwent fusion with 5/10 pain, and 1 patient experienced medial malleolar mal-union with 3/10 pain. Conclusion: It was found that the main reason for syndesmosis revision was reoccurring diastasis. Most patients ultimately experienced good reduction and were able to ambulate, despite some residual pain. Levels of Evidence: Level IV: Case series
